Yeast infection?

Hello!

Two weeks ago I started two antibacterial medicines. ( one being doxycycline) Which I have to take for the rest of the month.

Lately my vagina feels dry and hurts as if I’ve just had sex. Like when I wipe in the bathroom it cut me a little. It doesn’t burn when I pee, but I do feel really itchy. I have this white thick discharge but it doesn’t smell weird it just seems to surround my vagina.

Unsure if it’s the beginning of a yeast infection? Does anyone have any tips or ideas or have dealt with this?
